ETM issue
 

just had my etm repared by volvo diagnostics.com works fine also replased electronic throttle pedel all codes removed but ets light comes on after 2miles car runs fine any advice on the problem or just leave it

My ETS light comes on for a couple of weeks then goes off again for a week, been doing this for past 4 years. Codes show it's the post cat sensor which has no effect on the engine, it's only there to warn there may be a problem with the cat.
Last 4 MOTs indicate the cat is fine so I've left it as the sensor ain't cheap.
If the light is on there will be a fault code, just check what the code is and post on here if you have any doubts.
